For the greatest stability, this product should be retained with Stonemarket Trident Kerbs and an apron constructed of a Stonemarket concrete block paving product at the entrance of the driveway.

Drivegrid is membrane backed to inhibit weed growth; this plastic honeycombed cell is then filled with 5-16mm angular gravel. Stonemarket recommend this to be filled with Stonemarket Terracotta, Cotswold or Multi mix chippings.
